the Gui uses \Program Files\openvpn aswell in my case, when the GUI is starting at startup then it's adding
5 276 2001:db8:0:88::/64 On-link
aswell, but not after time a certain time after login, in 1 of 10 cases the Service don't add the On-link route and allow me as Client to communicate to 2001:db8:0:88::1, it's probably kinda sort of bug which add the dead route, could be Windows only issue, i got a workaround for that.
Edit: Service and GUI are same OS just for be clear.
My workaround is to route the Server IP through the Server IP
push "route-ipv6 2001:db8:0:88::1/128 2001:db8:0:88::1 1"
So i can ping and reach 2001:db8:0:88::1 always even when the dead route got added at the OpenVPN connect step.

So this config is working for me fine 100%, but it's kinda weird that some times the On-link route is getting added or not from the Client.
